`IIIIIVIPRITI-J1V.[I.El1"l".ll' IN LET-OFI AND TENSIQN DEVICES FOR SPOOLS OF BRAIDING-` MACHINES. Y y r The Schedule referred to in these Letters Patent and making part of the same.

To all whom tt may concern f Be it knownV that I, ,JAMES D. BUTLER, of Lan caster, county of Worcester, `and State of Massachusetts, have invented a new `and improved Braiding- Machine Traveler or Carrier; and I do hereby declare the following to bel a full description thereof', reference being had to the` accompanying drawings making part of this specification.

. My invention consists in an arrangement for the` yarn take-up and let-off in a braiding-machine traveler, in which simplicity of construction and effectiveness, of operation are combined, in a manner, for

certain kinds of Wol-k, superior to any heretofore known;` and` i Also, iu an improved form `of the traveler, as

adapted to the braiding-machinev proper. i

In iig'. 3 the spool and spool-spindle are omitted,

as they would interfere with the 'clear representation of the parts which need particularly to be seen. 4 `.A section of the spool-catch A is also given, in

preference to a complete view.

In iigS., 1 and 2, B represents 4the spool with the yarn wound upon it, and .i

C, the spindle, which is fast in the hub D, and upon which the spool turns.

.In figs. 1, 2, and 3, E represents the tensiondveight, 0

F, the check-weight;

A, the spool-catch; and 4 G, the upright upon which E and F slide.

E and G are of the form commonly used.

When the tension-wcightE is moved up by the drawing ofthe yarn, it strikes against the legs f of the check-weight Fand against the horns a of the catch A, and raises the` check-weight and spool-catch.

The raising of the spool-catch A'above the corners of the teeth b on the spool allows the spool to turn and let o yarn, and therefore should occur only when `more yarn is wanted from the spool.

f `Noww`here, as in the ordinary p1an,the tensionweight E strikes only against the spool-catch correspending to A, and thiscatch has no weightsupported upon it, the momentum of the vtension-weight i `willcause it to strike against and `raise the catch `after the thread has ceased to draw, provided the machine be run at a high rate of speed.

In this inventionthe spool-catch will not be raised by the tension-Weight'when the latter is moving by l its own momentum simply, as it evidently should not be, but will be when the yarn continues to draw the weight high enough, thus indicating that more yarn is really wanted from the spool, as it plainly ought to be.

The check-weight F may be about as heavy as the tension-weight E. When, therefore, E is thrown by its own momentum against F, it will itself stop, and its motion will be imparted to the latter.

- This motion of F does not disturb the catch A, as the former rests simply at f upon 'the latter. Thus F takes entirely the impulse from E which, were it not for it, would be given to the catch A, raising the latter and letting off' yarn from the spool.-

When, however, the thread continues to draw upon E after it has come against F, the former still rises, carrying the latter above it, and comes in contact with A at the ende of the horns, and lifts the catch, letting oi the required thread from the spool. 1

It will Ybe `seen that the check-weight F is supported upon the spool-catchA. This is a matter of convenience rather than a feature of' consequence.

It would answer toI have the check-weight supported, as' in gs. 4 and 5, upon a spur, g', on the `upright G upon which the weights slide.

The catch A', it is plain, can be raised without lifting the check-weight, and yet the check-weight acts just as well to protect the catch from the ten-v sion-weight as inthe arrangement shown in figs. 1, 2, and 3.

It will also be seen that the catch represented in figs. 4 and 5 slides upon the spool-spindle G, instead of swinging upon the Icop of the spool, as in iigs. 1, 2, and 3. v

In' figs. 6 and 7 the check-weight F" rests upon the spool-catch A, and is never touched by the tension-weight.4 Here the impulse which the catch receives from the tension-weight is entirely transmitted to the check-weight, so that the catch does not rise, but the check-weight instead.`

It is very easy to modifyconsiderably `the details of the parts entering into the above-described arrangement, and changes might bel kreadily made in the exact disposition, of these parts in reference to each other.

Ldo not confine myself to the details shown, inasmuch as I have set forth the advantages arising from the use of my form of check-weight, as guardrun rapidly. Y
